	Like Alain said, high ambient and HDRI only illuminate the scene
when using radiosity. In fact, when using an HDRI, you also need a
high ambient! The only difference is that an HDRI image has more
range, and therefore more precision between its brightest and
darkest points. This is useful for real-life pictures which have
naturally a very high dynamic range, but it is overkill in your case
since a poster in a bus stop has a low intrinsic dynamic range anyway.
